Straight-Arm Pulldown

Move · Resistance Training · Movement, Typed Supps

With the elbows locked, the whole arm becomes a long lever, so a light weight feels heavy and the lats get no help from the biceps.

Stage by stage

Set-up (Hinge sets the line of pull): Distance from the stack and a slight hip hinge determine where in the arc resistance torque peaks.
During the set (Whole arm as lever): A locked elbow makes the entire limb the resistance arm, so shoulder extension torque stays high at light loads.
Immediately after (Lats worked in isolation): With the elbow flexors excluded, fatigue is felt along the lats rather than in the arms.
Weeks later (Long-length lat loading): The overhead start loads the lats at long lengths, which complements but cannot replace heavy rowing.

Muscles trained

Primary: lats
Secondary: abs, rear shoulders, triceps

Intensity

3.5 METs (Resistance (weight) training, multiple exercises, 8-15 repetitions at varied resistance).

Time to effect

Weeks: The mind-muscle connection to your lats sharpens fast, since locked elbows leave the biceps with almost nothing to contribute.
Months: Lat width and the visible sweep down your sides develop, and you can maintain a strict, straight-arm bar path under progressively more load.

Common myth

"Keeping your arms straight makes this an easier version of a pulldown, since you're not curling any weight." In reality: Locking the elbows actually makes the lift harder for the biceps to sneak into, forcing the lats to generate the pulling force entirely on their own — that trade-off is the entire point of the straight-arm setup, not a way to lighten the load.
